The Goodyear Aircraft Corporation is a subsidiary of the Goodyear Tire and Rubber Company, well known as manufacturers of tyres and lighter-than-air balloons such as Explorer I, with a capacity of 28,500 cubic metres, which exploded at a height of 18,100m, and was followed by the helium-inflated Explorer II, which reached an altitude of about 36,750m. In 1925 Goodyear also produced non-rigid airships.

In 1954 the company produced a single-seater helicopter intended for the tactical requirements of transporting one man only.

This single-seater ultra-light helicopter, designed by Paul Ziegler, is powered by a water-cooled, two-cycle engine driving the rotors through a belt and pulley arrangement. The main rotor consists of two laminated blades balanced about the feather axes and mounted in a steel hub underslung from a teetering hinge. The airframe is constructed from welded tubing, and the landing gear is formed of parallel aluminium skids.

When used for training purposes the helicopter can be stabilized by the use of two persons, one supporting each side, until the trainee has acquired a thorough knowledge of the rotorcraft.

The first flight took place in 1954.

Well known for its airships, the Goodyear Aircraft Corporation developed a small open-frame single seat helicopter which made its first flight on 9 May 1954. This prototype (N62N) was designated GA-400R Gizmo and followed classic lines with the pilot seat on the forward frame, a narrow tailboom with a tail rotor and the 32hp Mercury 55 engine mounted amidships and driving a two-blade main rotor. It was followed by the GA-400R-2 and GA-400R-3 (N69N and N53A) which were powered by a 38hp Johnson two-stroke engine. Like many contemporary ultra-light helicopters the GA-400R did not progress beyond prototype stage.
